The pre-task on-screen instructions ask: "Has the card turned over?"
To begin the task, the test supervisor or subject must press the "Enter" key.
A playing card is presented in the center of the screen.
The card will flip over so it is face up. As soon as it does, the subject must press the "Yes" key.
The card will go to the back of the pack and the subject must press the "Yes" key as soon as the next card flips over and so on.
The subject should be encouraged to work as quickly as they can and be as accurate as they can. For example, they should try not to press the "Yes" key before a card flips over. If the subject does this or does not respond to a card that has flipped over in time, they will hear an error sound.
